Cleaning and maintenance
■ Your receiver is cooled by air circulated through the vents on the bottom
of the case. Keep these vents free of dust. With the receiver turned off and
unplugged, brush the dust away from the vents with a damp cloth. Be
careful not to drip any water into the vents. Do not attempt to clean dust
from the inside of your receiver.
■ Do not use abrasive or solvent cleaners because they can damage the finish.
■ Do not allow any excessive water or moisture to come into contact with
the surface of the receiver. If water or moisture gets inside your receiver,
operating problems and electrical and shock hazards may result.
■ Do not scratch or hit the case with your fingers or any hard objects.
